Alfa DNA SYSTEM
(Car dynamic control system)
This device allows, using lever 1 fig. 28
(on the central tunnel), four car response
modes to be selected according to
driving style and road conditions:
❒ d = Dynamicor Race
(sports driving mode);
❒ n = Natural(mode for driving in normal
conditions);
❒ a = All Weather(mode for driving in
poor grip conditions, such as rain and
snow).
28A0L0108
The lever 1 is a monostable, i.e. it always
remains in the central position.
The selected driving mode is indicated by
the corresponding LED switching on in
the panel and by an indication on the
display.
The device acts on the dynamic car
control systems (engine, steering, ESC,
ASR, ELECTRONIC Q2 systems, etc.).
“Natural” MODE
It is a manufacturer-recommended mode
aimed at comfort and safety in normal
grip and driving conditions.
“DYNAMIC“” MODE
IMPORTANT During the first 250 km of
car utilisation, the Dynamic and Race
modes are inhibited. Within this first
interval of start-up mileage it is advisable
to refrain from an aggressive driving
style, so that the best gear shifting
quality can be achieved over time.
Activation
Move lever 1 fig. 28 upwards (to the
letter “d”) and hold in this position for half
a second, until the corresponding LED
lights up and the “Dynamic” mode
activation indicator appears on the
display.
When released, lever 1 will return to
the central position.
Deactivation
To deactivate “Dynamic” mode and return
to “Natural”, move lever 1 fig. 28
downwards (to letter “a”) and keep it in
this position for half a second.
“Race” MODE
Activation
Move lever 1 fig. 28 upwards (to the
letter “d”) and hold in this position for 5
seconds, until the “Race” mode activation
indicator appears on the display.

WARNING LIGHTS AND MESSAGES
IMPORTANT The warning light switches on in the instrument panel together with a dedicated message and/or acoustic signal when
applicable. These indications are indicative and precautionary and as such must not be considered as exhaustive and/or alternative to
the information contained in the Owner Handbook, which you are advised to read carefully in all cases. Always refer to the information
in this section in the event of a failure indication.
IMPORTANT Failure indications displayed are divided into two categories: very serious and less serious failures. Serious faults are
indicated by a repeated and prolonged warning “cycle”. Less serious faults are indicated by a warning “cycle” with a shorter duration.
The display cycle of both categories can be interrupted. The instrument panel warning light will stay on until the cause of the
malfunction is eliminated.
